Changes in version 1.3-1 (2026-04-17) USER VISIBLE CHANGES o Mark the package as deprecated since R 4.6.0 incorporates all its functionalities. On R >= 4.6.0, the package uses the standard drivers and does not export the utility function SweaveGetSourceName. Behaviour for earlier versions remains unchanged. Changes in version 1.3-0 (2025-10-30) NEW FEATURES o Aliases weave and tangle for !ignore.on.weave and !ignore.on.tangle, respectively. USER VISIBLE CHANGES o Functions RweaveExtraLatexRuncode and RtangleExtraRuncode are now documented with their driver, like the corresponding functions in the package utils. Therefore, ?RweaveExtraUtils no longer exists. Changes in version 1.2-1 (2025-08-18) BUG FIX o SweaveGetSourceName could fail to identify the name of the source file on Windows for jobs started with R CMD Sweave. Changes in version 1.2-0 (2025-03-14) NEW FEATURES o Option chunk.sep for the driver RtangleExtra to control the spacing between code chunks in the tangled script. o Function SweaveGetSourceName to extract the name of the file processed by Sweave or Stangle in a non-interactive session. USER VISIBLE CHANGES o The default value of option extension is now TRUE. This is the value that will use the name of the engine as extension. The value NULL is now equivalent to FALSE. Changes in version 1.1-0 (2024-02-20) NEW FEATURES o Option extension for the driver RtangleExtra to specify the extension of the file name (or remove it entirely) when splitting is selected on tangling. Changes in version 1.0-0 (2021-05-28) o Initial release. The additional options for the weaving and tangling drivers of Sweave are ignore.on.weave, ignore.on.tangle and ignore.
